Question details

Users with an active Microsoft 365 subscription are encountering an Unlicensed Product error message when trying to use Word and Excel.

Product: Microsoft 365 (Word, Excel)
Device & OS: not provided
Scenario: Opening and attempting to use Microsoft Office applications with a valid subscription.
Observed behavior: Word and Excel display an Unlicensed Product message in the application header. This is often triggered by duplicate or conflicting Office language packs interfering with the software's license recognition process.

Before you start

Verify that your Microsoft 365 subscription is active via your Microsoft account dashboard, and save any open documents as you will need to restart your applications.

Solution 1Recommended

Remove Duplicate or Conflicting Language Packs

Uninstalling unnecessary language packs resolves conflicts that prevent Microsoft 365 from properly verifying your subscription license.

Multiple installed versions of Office language packs can sometimes confuse the Microsoft 365 licensing service. Removing the duplicates allows the software to accurately read your active subscription.

Open Windows Settings

Press the Windows key, type 'Settings', and hit Enter. Navigate to 'Apps' and then select 'Installed apps' or 'Apps & features'.

Locate Office Language Packs

Scroll through your installed applications or use the search bar to look for 'Microsoft Office Language Pack' or 'Microsoft 365'.

Uninstall Duplicates

If you see multiple language packs (especially ones you do not actively use), click the three dots next to the extra pack and select 'Uninstall'.

Restart Office Applications

Close any open instances of Word and Excel, then relaunch them to see if the Unlicensed Product message has disappeared.

Restart Required: Changes to Office language packs will only take effect after the applications are completely closed and reopened.

Solution 2

Verify Your Office Account Status

Check your in-app account settings to ensure the software is attempting to authenticate the correct Microsoft account.

Frequently Asked Questions

Why does Microsoft 365 say Unlicensed Product when I have an active subscription?

This error typically occurs when the Office applications cannot verify your license. It can be caused by conflicting Office language packs, temporary network issues, or being signed in with an incorrect Microsoft account.

Will uninstalling an Office language pack delete my documents?

No. Uninstalling a language pack only removes the localized user interface and proofing tools (like spell check) for that specific language. Your saved documents and personal data remain completely unaffected.

How do I check which language versions of Office I have installed?

Open Word or Excel, go to File > Options, and select 'Language' from the left pane. Here you can view your Office display language and authoring languages. To see installed packs on a system level, check Windows Settings > Apps.

What should I do if the Unlicensed Product error persists after removing language packs?

If the issue remains, try signing out and back into your Microsoft account within the Office app, run the Microsoft Support and Recovery Assistant (SaRA) tool, or contact official Microsoft support for further assistance.
